steveh Ex Member	Re: chain drive conversion Reply #15 - 02/18/07 at 13:57:50 I measured the sprockets that were installed on the 87: the front sprocket has 15 teeth. the rear sprocket has 47 teeth and is marked "47-530." The sprockets appear to be in reasonably good condition if anyone is interested in buying them.

Well, of course, it is your idea, so if you want it I guess I should let you get it.

Why? All the reasons that have been mentioned actually. The belt can be a spare for my spouse's. Mine's been a conversion project since the beginning,

Besides, with my drag pipe, the bike would do well on top end.

I n the middle of all the pictures, I came up with a new breakdown, This one is the change in speed for each gear. Keep in mind I am using 6400RPM as shift point.

(STOCK)------------------------------------------(17/45)

1ST 0-35-------------------------------------------- 0-39
2nd 35-55------------------------------------------ 39-61
3rd 55-75-------------------------------------------- 61-83
4th 75-90-------------------------------------------83-100
5th 90-100----------------------------------------100-111

This is the specs from the manual for stock at 6400RPM, and conversion at 6400RPM. There is a 2.5% change for every tooth you add or subtract from the rear sprocket. The stock ratio is 2.96:1 and with the 17/45 it is 2.65:1 That works out to a 10% change in RPM and speed with the new ratio.

You will be going the wrong way with the 15/ 47 sprockets. 18/47 would work, if 18 will fit???

anyone thought of trying to find a smaller 5th gear sprocket and doing the swap at the transmission level. that way you still retain all of your torque, but turn fifth into an overdrive. Or am I smokin' crack and this is not possible?

Bike bandit says the sprocket is a 23 tooth going to maybe 20 or even 19 might really improve things. Don't know what that would turn the fifth gear ratio into someone else can do that calc.

Oh and for those with the newer 650's the 5th gear is 25 teeth. FYI

Allan I went to the link above and there is no gt750 listed, is it called something else in the USA?? Check out the link, MAYBE I'm blind.it is getting late here. At least for us old farts. This post is for allan from manchester, but if anyone else knows, that would be cool also.

I new there was a reason the S-40's turned more r's with less top end than the Savage. My ears are still working after all. I thought I was going crazy, but I guess not.

I was specifically referencing the GS550, I think i saw it referenced earlier. Sorry for the confusion.

No problem tbalam, It was Allan from Manchester England that said you could use gt750 rear sprockets, and I can't find a listing for one. Some times European models have different names for the same bike in the USA.The GS550's biggest back sprocket is 40 and I need a 44 to work. That is why I wanted to find the illusive GT750 Allen was talking about. Man I have been on this computer for 15 hours and I can't even spell any more. GOODNIGHT!!!!

3rd 55-75-----------------------------------------62-85
4th 75-90-----------------------------------------85-102
5th 90-100--------------------------------------102-113

This is the specs from the manual for stock at 6400RPM, and conversion at 6400RPM. With the gears you are looking at Greg, yours would be going the other way. Stock is 2.96:1 and yours would be 3.13. Mine will be 2.59:1 If you can squeeze a 18 tooth on the front with the 47 on the rear you would end up with a 2.61:1 ratio. Darn close to the 2.59:1 chart figures

Well, actually while I've been away I've been trying to figure out where the sprockets came from and how they ended up on the Savage. So far, not any real info except that I found that the GN 400 had a 37 tooth on the rear with a 520 chain.

I think that I got all confused on this post. Too many numbers. I thought that Steveh said 17/47 which is 2.76:1. But now I see 15/47. Crap.

Okay. On to the question about bolt pattern...

I had to go back to the "Ton" post.

1986-1988 - 4 speed ratios:
1st- 2.214
2nd-1.500
3rd- 1.095
4th- .875

1995-2005 - 5 speed ratios;
1st- 2.333
2nd-1.578
3rd-1.142
4th-.956
5th-.884

And don't forget that the primary reduction ratio changed:

'86 -'88 - 1.88 with the gears 68 and 36.

After that - 1.81 with the gears 67 and 37.

so the later models went higher from 1-3 and lower in 4-5.
